saw GUMMER.

To all whom it may concern:

Be it known that I, REDMOND F. BARRY, a citizen of the United States,residing at Republic, in the county of Ferry and State of lVashington,have invented new and useful Improvements in Saw Gummers, of which thefollowing is a specification.

My present invention has reference to a gumming machine.

An object is the production of a saw gummer including a base having apocket therein for a die on which the saw rests and having an openingcommunicating with the pocket for the passage of waste, a springinfluenced punch being arranged above the die in a position to engagewith the saw, and revoluble means being provided for actuating the dieto bring the same to operative position, the spring returning the die toinitial or inoperative position when the rotary means have turned in anopposite direction to that first mentioned.

A. further object is the production ofv means whereby punches of varyingsizes to accommodate varying classes of saws are employed, the samebeing removable and spring influenced to inoperative position, thespring remaining a permanent part of the device, while a revolubleelement in the nature of a screw contacts with the die to move the sameagainst the saw, and when turned in an opposite direction permits of thespring re turning the die to its initial position.

A. further object is the production of a saw gummer which shall be of acomparatively simple construction, cheaply manufac tured and marketed,easily operated, and thoroughly eficient in operation.

The foregoing objects, and others which will appear as the nature of theinvention is better understood, may be accomplished by a construction,combination and operative arrangement of parts, such as is disclosed bythe drawings.

In the drawings:-

Figure l is an elevation of a saw gummer constructed in accordance withthis invention.

Figure 2 is an end view thereof.

Figure 3 is a sectional view approximately on the line 33 of Figure 2.

Figure 4 is a sectional view approximately on the line 4-4 of Figure 1.

Figure 5 is a sectional view approximately similar to Figure 3, butillustrating a modification.

Specification of Letters Patent.

Patented June 6, 1922.

Application filed July 17, 1920. Serial No. 397,001.

Figures is a transverse sectional view therethrough.-

Figure 7 is a horizontal sectional view extension 6 which overlies thebase, the said extension providing what may be termed the head of thedevice, and the said head is formed with a depending socket portion 7which is arranged directly over a vertical opening 8 in the base.- Thevertical opening communicates with a transverse opening 9, and throughthese openings the waste passes. The base, upon its upper face has asubstantially rectangular pocket 10, within which is seated a tie 11.The tie has its edges provided with openings 12 which register with theopenings 8 and 9 so as not to interfere with the passage of the wastethrough the last mentioned openings, and also so'as to provide a passagefor the pointed end of the punch members 13.

The bore of the socket 7 is preferably octagon shaped as are the shanks14 of the dies 13. The pointed ends 15 of the dies 13 have their sidesconverging to the sides of the shank 14, and each of the substantiallyrectangular points is notched on one of its edges, as at 16, theshoulder provided by the notch being engaged by the end of an archedspring 17 which is secured to the inner face of the upstanding portion 5of the base structure. Each shank of the dies 13 preferably has itsouter face formed with a concavity which is designed to be engaged bythe rounded end of the operating screw 18. The screw is received in thethreaded bore of the head which communicates with the socket thereof,the outer end of the said screw is formed with a rectangular head 19having angularly arranged openings 20 therethrough, and through two ofthe aligning openings is passed the removable handle which is in thenature of a rod 21.

It will be apparent that when the screw is turned in a screwingdirection the punch will be projected through the socket so that the bitthereof will operate on the saw. The waste material will drop into aslot in the die or bed plate through the openings 8 and 9. By turningthe screw in a reverse or unscrewing direction, the spring will act onthe punch to bring the same out ofsaw engaging position, and thus ingumming the saw the screw is constantly turned in both of a circularcross section, the rounded face 50 of which has a groove 51therethrough, and the groove 1s designed to receive thereln a guidefinger 53.

Having thus described the invention, what I claim, is

A device of the class described compris ing a base having a transverseopening in the lower side thereof and provided with a vertical openingin communication with the transverse opening, ears extending from saidbase and provided with openings, said base having a pocket formed in theupper side thereof, a tie located in said pocket and having its edgesprovided with openings adapted to register with the vertical opening inthe base, an upstanding member extending from said base and providedwith a lateral extension, a socket extendlng downwardly from saidextens1on and disposed over the vertical opening in said base, said;

socket having a threaded bore at its upper end, a punch member engagingthe lower end of said socket and provided wlth a notch,

an arched spring means for guiding said punch member in said socketsecured to the upstanding member and engaging the notch in said punchmember, an operating screw engaging the upper end of said socket andadapted to engage said punch member and a handle removably secured tosaid screw.

In testimony whereof I afiiX my signature.

REDMOND F. BARRY.
